Plant Growth and Needs Assessment

The video tutorial introduces the lesson on the survival of organisms, focusing on the needs of plants. It covers the essential requirements for plant growth, including water, air, nutrients, space, and light. The teacher highlights important points from the textbook and discusses how plants absorb water and nutrients through their roots. The importance of light and space for photosynthesis and growth is emphasized. An example of hydroponics is provided, showing how plants can grow in water without soil if they receive necessary nutrients. An activity is conducted to observe plant growth in different light conditions, leading to a discussion on the impact of sunlight on plant health. The lesson concludes with a summary and closing remarks.

What was the main variable in the plant growth activity?

• Amount of water

• Amount of sunlight

• Type of plant

• Type of soil

Why did one plant grow taller and greener in the activity?

• It was in a sunny location

• It had more space

• It received more water

• It was a different species

What happens to a plant that receives less sunlight?

• It produces more flowers

• It becomes less green
